' accompanying. drawing, in whichview in elevation of .my .improved heater with the enclosing jacket'or case removed and with parts brokenaway to show construction. p

Figure 2 is a top view with partsbroken away to show construction.v V

Figure '3 .'s a view in' cross-section on a .plane denoted by the dotted line 33 t Figure1.'

Figure 4;. is a bottomzview with parts brokenaway: to show construction; 1 The base of my improved heater is preferably composed of three-sections, 'a gas receiving section 6, a water inlet section 7 and a tube supporting section 8. The section -,6 comprises-a bottomwith a flange risingtherefrom creating a recess that, when closed by the section 7, constitutes a gas chamber-9. Thesect-ion 7has a hub 10 extending into-the gas chamber with awater inlet 11 in the hub to pipe extending through the gas chamber. The passage 11 communicates with radially extending distributing 'passages'13, there be Figure 1 is a ingpreferably two of these passages extend ing from s1de to side oithe intermediate'se'ction and openingnat the edge thereof, said passages the section. The ends of thepassages are closed by screw plugs 14, andthe sections 6 and' 7 may be secured together in any suitable m'anner. An opening 15' istormed in the bottom of the lower sections for attach ment of a gassupply tube. Three sets of gas tubes are secured to the -section7, extending completely therethrough and opening into the gaschamber 9; These tubes also extend through a central opening :in the section "8 whicha water inlet pipe 12-issecured,-said crossing each other at thecenter of :terior of the case for lighting, or for other. purposes, and with suitableepenings to proof he base, the tubes 16 of one set having tips located ashortsdistance' from the top of the section 8 of the base, the tubes 17 of another set having-their tips located a little further from said'section, and the tubes 18 having their tipped ends located still further from the section 8. i r s The tube supportingsection 8 has an annulargroovef19 tormedlin its under surface.

this groove being closed by the top of the sec,-

, tion 7, thereby constituting-a passage having ports 20 openinginto the passages 13, and as shownin Figure 1 of the drawing. Two concentric-rows ofholes 21,. and 22 are formed 1 through the section 8, each row of holes cut ting into the groove 19 so that substantially one-halfof each holeintersects the groove 7 and the remaininghalf of each holeconstitutes a recess 23 in the side ofthe groove.

.Two {concentrically disposed rows 2425 of 1 tubes. are. secured in the holes 21 and 22 and rise, therefrom for agconsiderable distance 7 above :the ends of the gas tubes 18...

The top of thestructure'consists of two sections, a tube receiving section 26'and a water outletsection 27 secured together in any suit- :able, manner; The 1 section 26; is a duplicate of the section 8 at the bottom of the structure, .havlng rows of holes 21-,22, the groove 19,

the two rows ofholes being arranged as in the .bottom. section with the recesses 23 formed inthe sidesof-the groove 19. The

section 27 is, substantially a duplicate of the corresponding section 7,.at the bottom of the heater, having ports 20, collectingpassages 13 and an outlet passage 28corresponding to the inlet passage 11, an outletpipe 29 being securedtogthe section for [delivery of water from the heater 1 Y 7 As hereinbefore mentioned, a jacket or case'may 'be-applied inany suitable manner to'enclose the gas and water tubes, said jacket "having a suitable jdoorffor access to the invide for ventilation.

In accordance with theprovisions' of the patentstatutes, I have described the principles of operation of my invention, together with the device whichI nOwconsider to :rep- 7 00 resent the best embodiment thereof; but I desire to have it understood that the device shown is only illustrative, and that the invention may be carried out by other means and applied to uses other than those above set out.

I claim:

1. A liquid heater including a base, composed of a gas receiving section having a pe ripheral flange to create a recess, an inlet section resting on said flange to close said re-' cess and thereby create a gas chamber, said inlet section having passages therein, an in let pipe extending through said gas chamber and communicating with said passages, tubes communicating with said passages and extending upwardly from said base, means at the top of the-structure for collecting liquid delivered by said tubes, and gas tubes communicating with said" gas chamber and extending upwardly within the space bounded by said tubes, I

. 2. A liquid heater including a base composed of a'gas rcceivingsection having a peripheral flange to createa recess, an inlet section resting on said flange to close saidrecess and thereby create a gas chamber, said inlet section having a passage extending inwardly at the center thereof and communlcating with passages extending crosswise of each other across the section, an inlet pipe extending through the gas chamber intosaid inlet passage, ports opening out of said crosswise passages, tubes communicating wlth said ports and extending upwardly from said base, means at the top of the structure for collecting liquid deliveredby said tubes, and gas tubes communicating with said gas chamber and extendingupwardly within the space bounded by said liquid tubes. g

3. A liquid heater comprising a base 1ncluding a tube supporting section having an annular groove with recesses located at intervals in the sidewallsof the groove and holes extending into said recesses, means for delivering liquid to said groove, a gas chamber,

gas tubes communicating with said chamber and rising from the base, tubes securedin said holes and rising from. the base, and means at the top of the structure for collecting liquid delivered by said tubes.

4. A liquid heater comprising a base including a tube supporting section having an annular groove in its flat surface, said groove having recesses in the sides thereof with holes 7 opening throughthe section into said recesses,

a plate supporting said'section and closing said groove, said plate having passages'to deliver liquid to said groove, tubes'secured in said holes and rising from the base, gas pipes rising within the'space bounded bysaid tubes,

'means for supplying gas to said pipes, and -means at the top of the structure for collecting liquid delivered by said tubes.

5. A liquid heater comprising a base havsaid holes and rising from said base, gas

pipes extending from said gas chamber upwardly within the space bounded by said tubes, and means at the top of the structure for collecting liquid delivered by said tubes.

6. A liquid heater comprising a base including atube supporting section with an annular groove therein, recesses inthe side walls of the. groove and holes opening into said recesses,said base'having a gas chamber, means for supplying liquid to said groove, means for supplying gas to said gas chamber, gas pipes communicating with said chamber and rising from the base, tubes secured in :said holes and rising from the base, a tube: receiving section in the top of the structure of duplicatefconstruction to the tube supporting section at the bottom, and means at the top of the structure for collecting liquid delivered by said tubes.
